I try to be less ambiguous: my scene is a small room with a table at the center. The table, how you can see in pics has 8 rods, The table is translated by (0, 0, -309) to be placed on the floor My goal is to rotate a rdd using the mouse wheel: when i pick & scroll up on a rod it should rotate the related rod by +angle (the variable rotation in code) on Y axis (-rotation if i scroll down).

Re: [osg-users] Improper rotation
I understood part of the issue, and thus I corrected (part of) the error. Now
seems that the rotation and the translation is formally right, but visually
translation is wrong. I enclosed 3 pics of the scene, before rotating, after
1st rotation and after 2nd rotation. I correct the source as follows:
Code:
printVector("Original amtRod trans: ",
amtRod->getWorldMatrices()[0].getTrans());
printVector("Original amtRod rotate: ",
amtRod->getWorldMatrices()[0].getRotate());
printVector("\t amtRod center: ",
amtRod->getBound().center());
osg::Vec3 offset = amtRod->getWorldMatrices()[0].getTrans();
printVector("\t amtRod offset = ", offset);
osg::Matrix get = osg::Matrix::translate(- offset);
osg::Matrix m = amtRod->getMatrix() *
osg::Matrix::rotate(rotation, osg::Vec3(0,1,0));
osg::Matrix put = osg::Matrix::translate( offset);
amtRod->setMatrix( get * m * put );
printVector("\t get.getTrans = ", get.getTrans());
printVector("\t m.getRotate = ", m.getRotate());
printVector("\t m.getTrans = ", m.getTrans());
printVector("Current amtRod trans: ",
amtRod->getWorldMatrices()[0].getTrans());
printVector("Current amtRod rotate: ",
amtRod->getWorldMatrices()[0].getRotate());
Now the output is:
Original amtRod trans: (0, 0, -309)
Original amtRod rotate: (0, 0, 0)
amtRod center: (6.55547, 150.952, -142.15)
amtRod offset = (0, 0, -309)
get.getTrans = (-0, -0, 309)
m.getRotate = (0, -0.130526, 0)
m.getTrans = (79.9751, 0, -298.471)
Current amtRod trans: (0, 0, -309)
Current amtRod rotate: (0, -0.130526, 0)
Original amtRod trans: (0, 0, -309)
Original amtRod rotate: (0, -0.130526, 0)
amtRod center: (-36.8519, 150.952, -146.139)
amtRod offset = (0, 0, -309)
get.getTrans = (-0, -0, 309)
m.getRotate = (0, -0.258819, 0)
m.getTrans = (79.9751, 0, -298.471)
Current amtRod trans: (-74.5249, 0, -339.869)
Current amtRod rotate: (0, -0.258819, 0)
Are there suggestions?

[osg-users] Improper rotation
Hi,
i'm trying to rotate a rod (part of a 3rd party model) on its Y asxis. I read
on OSG Startguide that to do it, i need to find the correct position of my
object from the origin and apply a multiplication like T * M * -T.
The source code that tries to do it is the follow
Code:
ing:
printVector("Original amtRod trans: ",
amtRod->getWorldMatrices()[0].getTrans());
printVector("Original amtRod rotate: ",
amtRod->getWorldMatrices()[0].getRotate());
printVector("\t amtRod center: ",
amtRod->getBound().center());
osg::Vec3 offset = amtRod->getWorldMatrices()[0].getTrans();
printVector("\t amtRod offset = ", offset);
osg::Matrix get =
osg::Matrix::translate(-amtRod->getBound().center() - offset);
osg::Matrix m = amtRod->getMatrix() *
osg::Matrix::rotate(rotation, osg::Vec3(0,1,0));
osg::Matrix put = osg::Matrix::translate(
amtRod->getBound().center() + offset);
amtRod->setMatrix( get * m * put );
printVector("\t get.getTrans = ", get.getTrans());
printVector("\t m.getRotate = ", m.getRotate());
printVector("\t m.getTrans = ", m.getTrans());
printVector("Current amtRod trans: ",
amtRod->getWorldMatrices()[0].getTrans());
printVector("Current amtRod rotate: ",
amtRod->getWorldMatrices()[0].getRotate());
(printVector only prints the osg::Vec3 or a osg::Quat in a file).
The result isn't what i expect, since it rotates the rod but also translate it,
as the following output demonstrates:
Original amtRod trans: (0, 0, -309)
Original amtRod rotate: (0, 0, 0)
amtRod center: (6.55547, 150.952, -142.15)
amtRod offset = (0, 0, -309)
get.getTrans = (-6.55547, -150.952, 451.15)
m.getRotate = (0, -0.130526, 0)
m.getTrans = (79.9751, 0, -298.471)
Current amtRod trans: (-36.5678, 0, -315.54)
Current amtRod rotate: (0, -0.130526, 0)
What's wrong in my reasoning?
Thank you for help!
Cheers,
Axel

[osg-users] Can't apply rotations
Hi,
I added the pickHandler to my application, and then I applied some changes in
it to rotate a rod (that is part of an imported osg model) when scrolling the
mouse on its handle (a geode).
It picks correctly, but doesn't perform the visual rotation... here is the
relevant code fragment:
Code:
void BabyFootManipulator::_pickRotate(osgViewer::View* view, const
osgGA::GUIEventAdapter& ea, double rotation) {
osgUtil::LineSegmentIntersector::Intersections intersections;
float x = ea.getX();
float y = ea.getY();
if (view->computeIntersections(x, y, intersections)) {
for (osgUtil::LineSegmentIntersector::Intersections::iterator hitr =
intersections.begin();
hitr != intersections.end();
++hitr) {
if (!hitr->nodePath.empty() &&
!(hitr->nodePath.back()->getName().empty())) {
// the geodes are identified by name.
osg::Node* node = hitr->nodePath.back();
if (node->getName() == "handle") {
osg::notify(osg::ALWAYS) << "\n\tFound handle.. " ;
osg::Group* parent = node->getParent(0);
osg::Group* grandpa = parent->getParent(0);
osg::Transform* t = grandpa->asTransform();
osg::MatrixTransform* mtRod = t->asMatrixTransform();
mtRod->setDataVariance(DYNAMIC);
osg::notify(osg::ALWAYS) << grandpa->getName() << ": " <<
grandpa->className() << std::endl;
osg::Matrix m = mtRod->getMatrix() *
osg::Matrix::rotate(rotation, osg::Vec3(0,1,0));
mtRod->setMatrix( m );
printVector("\t m.rotation = ", m.getRotate());
osg::notify(osg::ALWAYS) << "\tRotation done" << std::endl;
return;
}
}
}
}
}
The output related to that code, when i scroll upon the handle is this:
Found handle.. mtRod: MatrixTransform
m.rotation = (0, -1.00629e-231, 0)
Rotation done
Found handle.. mtRod: MatrixTransform
m.rotation = (0, -2.01257e-231, 0)
Rotation done
Found handle.. mtRod: MatrixTransform
m.rotation = (0, -3.01886e-231, 0)
Rotation done
Found handle.. mtRod: MatrixTransform
m.rotation = (0, -4.02514e-231, 0)
Rotation done
Found handle.. mtRod: MatrixTransform
m.rotation = (0, -5.03143e-231, 0)
Rotation done
Found handle.. mtRod: MatrixTransform
m.rotation = (0, -6.03771e-231, 0)
Rotation done
Found handle.. mtRod: MatrixTransform
m.rotation = (0, -7.044e-231, 0)
Rotation done
...
So, how you can see, the matrix is updated, but i can't see any visual
rotation. What's wrong on my code? What do i forget?
I alwo tried to change the axis of rotation or to apply a translation instead
of a rotation, but the result is the same...
Can someone help me?
Thank you!
Cheers,
Axel

To change project or to continue trying to install collada-dom + osg + bullet physics on a 32-arch of Ubuntu? Please, let me know your opinion.. i need the advise of experts like you two :) Thank you very much Cheers, Axel [1] http://sketchup.google.com/3dwarehouse/details?mid=6f7074fb94c1f777bb1356f47c7f12bb [/url] -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=33371#33371 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] OSG, bullet physics, collada and sketchup models on Ubuntu
Thank you jordi, now i begin to read the link you've suggested. Unluckily on Google warehouse i can find only skp files for the model i look for :-( However, with a quick search i've seen that the is some tool to convert skp fines in 3ds format... maybe i could convert skp in 3ds and 3ds in dae :P I hope to be more lucky now :-) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=33322#33322 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] OSG, bullet physics, collada and sketchup models on Ubuntu
Hi all, i correctly installed osg 2.8.1 (by apt - ubuntu/debian package manager) and bullet physics 2.76 building the sources. When i tried to load a sketuchup file (.skp) osgviewer reported an error. I read that i need collada-dom to load this kind of model. Is it right? However, i also tried to build collada, but there are a lot of bugs for linux and seem to be no more supported... i fixed some of them but not all. So i seen that bulet physics 2.75 (an older version) have collada included in its sources and i tried to build it too :P (hope successfully). Now i think i have to re-installe the osg by sources selecting also the collada plugin. Is this right? Since i installed in past also osgWorks and osgBullet, and had some problem with bullet physics, i think there's a lot of garbage in my libraries and maybe i need to reinstall the whole Ubuntu... To prevent future problems can anyone answer to next questions? 1) Does OSG need collada to load sketchup files? 2) Is there anyone who succesfully installed collada-dom on ubuntu/linux? 3) can anyone provide me a link to a really good tutorial to install collada-dom and load sketchup files using osg? I'm quite desperate, i've lost a lot of days... :-( Thank you!

Re: [osg-users] Really stupid question about creating a new osg program on linux
Thanks to both, now my app is correctly compiled and built with both solutions. Now i just have to think how to integrete them to work with osgBullet libraries ;-) Thank you again!

[osg-users] Really stupid question about creating a new osg program on linux
Hi aa, i know that my problem is probably really stupid, forgive me! I'm novice of C++ and i need to create a small scene with osg libraries. So i successfully installed osg-sdk on my ubuntu 9.10 by apt, downloaded the sample datasets and configured environment variables. If i launch osgviewer cow.osg it works correctly. So i created a new executable c++ project in Eclipse and as main project file i copied/incolled the osgviewer.cpp source. When i try to build this project, it reports this errors: Building file: ../src/osgviewer.cpp Invoking: GCC C++ Compiler g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/osgviewer.d" -MT"src/osgviewer.d" -o"src/osgviewer.o" "../src/osgviewer.cpp" Finished building: ../src/osgviewer.cpp Building target: osgviewer Invoking: GCC C++ Linker g++ -o"osgviewer" ./src/osgviewer.o ./src/osgviewer.o: In function `main': /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:34: undefined reference to `osg::ArgumentParser::ArgumentParser(int*, char**)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:36: undefined reference to `osg::ArgumentParser::getApplicationName() const' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:37: undefined reference to `osg::ArgumentParser::getApplicationName() const' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:38: undefined reference to `osg::ArgumentParser::getApplicationName() const' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:39: undefined reference to `osg::ApplicationUsage::addCommandLineOption(std::basic_string, std::allocator > const&, std::basic_string, std::allocator > const&, std::basic_string, std::allocator > const&)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:40: undefined reference to `osg::ApplicationUsage::addCommandLineOption(std::basic_string, std::allocator > const&, std::basic_string, std::allocator > const&, std::basic_string, std::allocator > const&)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:41: undefined reference to `osg::ApplicationUsage::addCommandLineOption(std::basic_string, std::allocator > const&, std::basic_string, std::allocator > const&, std::basic_string, std::allocator > const&)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:43: undefined reference to `osgViewer::Viewer::Viewer(osg::ArgumentParser&)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:46: undefined reference to `osg::ArgumentParser::readHelpType()' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:47: undefined reference to `osg::ApplicationUsage::write(std::basic_ostream >&, unsigned int, unsigned int, bool)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:52: undefined reference to `osg::ArgumentParser::errors(osg::ArgumentParser::ErrorSeverity) const' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:53: undefined reference to `osg::ArgumentParser::writeErrorMessages(std::basic_ostream >&, osg::ArgumentParser::ErrorSeverity)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:58: undefined reference to `osg::ApplicationUsage::write(std::basic_ostream >&, unsigned int, unsigned int, bool)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:64: undefined reference to `osgDB::Registry::instance(bool)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:65: undefined reference to `osgDB::Registry::instance(bool)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:69: undefined reference to `osgDB::Registry::instance(bool)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:63: undefined reference to `osg::ArgumentParser::read(std::basic_string, std::allocator > const&, osg::ArgumentParser::Parameter, osg::ArgumentParser::Parameter, osg::ArgumentParser::Parameter)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:77: undefined reference to `osgGA::TrackballManipulator::TrackballManipulator()' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:77: undefined reference to `osgGA::KeySwitchMatrixManipulator::addMatrixManipulator(int, std::basic_string, std::allocator >, osgGA::MatrixManipulator*)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:78: undefined reference to `osgGA::FlightManipulator::FlightManipulator()' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:78: undefined reference to `osgGA::KeySwitchMatrixManipulator::addMatrixManipulator(int, std::basic_string, std::allocator >, osgGA::MatrixManipulator*)' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:79: undefined reference to `osgGA::DriveManipulator::DriveManipulator()' /home/omi/eclipseWorkspace/osgviewer/Debug/../src/osgviewer.cpp:79: undefined reference to `osgGA::KeySwitchMatrixManipulator::addMatrixManipulator(int, std::basic_string, std::allocator >, osgGA::MatrixManipulator*)' /home/omi/eclip

[osg-users] [build] Problem building OsgWorks on Ubuntu
Hi all, i'm a newbie of OSG and quite a newbie on Linux. I've to create a small project for my studies using OsgBullet. Reading about it i've seen that it depends on OpenSceneGraph, OsgWorks and Bullet. I installed OpenSceneGraph using apt-get, and then i tryed to build & install OsgWorks by CMake-GUI and here comes my problem: the configure & generate process finish well but i don't know how to do after that. I haven't found a guide or how-to that explains the next steps in detail... going in the build-directory and typing make the compiler returns syntax errors. Can anyone help me suggesting a detailed how-to or listing the instruction to complete my installation? Thank you.
